Problem 1E

In a study comparing various methods of gold plating, 7 printed circuit edge connectors were gold-plated with control-immersion tip plating. The average gold thickness was 1.5 µm, with a standard deviation of 0.25 µm. Five connectors were masked, then plated with total immersion plating. The average gold thickness was 1.0 µm, with a standard deviation of 0.15 µm. Find a 99% confidence interval for the difference between the mean thicknesses produced by the two methods.
